LMTP and [E]SMTP are indentical except for the hello commands, so making
lmtpd handle [E]SMTP is trivial, but I don't see the point. Cyrus is
not designed to be an MTA, and I don't think you want to spend the time

Sieve does get the envelope, but it has no facilities for checking IP.
You might want to consider having your MTA do this type of SPAM checking
globally and adding an X-SPAM header which can then be filtered by
individual users via Sieve.
